Would you buy this Mold, .223 /5.56gr.GC

[runfiverun]

let's see what everybody else say's.
making the second drive band a little bigger would add another couple of grains of weight.
not gonna hurt my feelings and it would benefit the 7 and 9 twist barells.
as well as shift the weight a titch more center/rearward which is an accuracy enhancer.

edited to add felix has an excellent idea as usual.

No, I would not buy one for all the reasons Bullshop and runfiverun mention. The only reason to buy a 60+ gr cast .223 bullet is for faster AR twists of 7, 8 and 9" twist barrels. There is just too much unsupported nose hanging out there. Better to have (if you realistically want any hope of accuracy above the mid teens in fps with such ast twists) GC and lube groove inside neck, maximum bearing surface on bore riding nose and a 1R or 2R short nose giving a 62 - 65 gr fully dressed weight.

I would definately buy a 55 grain fn mold. This is the last caliber that I use jacketed in.

So does any one have any more improvements thy would like to see on the current flat nose design?

[dnotarianni]

OK What is the actual design and not to start problems is there a brass block option. Also what is expected time frame for delivery. Got cash but no patience

Well maybe just one little thingy like maybe a trouth type sprue plate.
Did I mention that I like talking boolit design?
Did I mention that maybe I talk too much?

[nanuk]

is it just me, or do the nose lengths not add up?

[Springfield]

I liked the spacing on the original mould better. The 2" would work well for 4 cavity, though. Sorry for any confusion. Not saying the second design wouldn't work, just seems a bit crowded, but maybe not. Time will tell. And personally I like the round nose as I already have a flat nose NOE, so I like those also.

[runfiverun]

they don't quite add up in length because of the meplat-radius difference.
that little difference is why i wanted the flat nose.
it might be cleaner/easier to make a single trough instead of several radiused sprues.
and easier to keep heat in the sprue plate too.

changes or not i trust jt's machining skill-[mold judgement] and i'm still in.
i have seen his work first hand, it's neat and clean.

"""it might be cleaner/easier to make a single trough instead of several radiused sprues.

Yes and is why I mentioned it. But since it may have seemed I was belittling the original design or kinda just complaining about it and since I am uncommited I was kinda getting worried I might get told to mind my own as at time I know I should.

[runfiverun]

you are trying to improve the product, and aren't changing anything i don't agree with.
if the changes are incorporated before manufacturing begins it's no big deal as they just become the process.

[MT Gianni]

I like the 62 gr version and the tighter blocks. I cast with several trough type sprue plates with great results. I do shoot 1 in 9 and 1 in 7.5 " twists and like the looks of this.

[JTknives]

I will draw up a single trough plate design tomorrow morning. I'm guessing each sprue hole will have a small fill cone connected to the others with a trough. PLEASE if you have any tips or ideas share them. This is not just about the 223 but also perfecting the molds them selves.

[Wilkie]

Are you still thinking this will be in the $125 range?

[JTknives]

Are you still thinking this will be in the $125 range?

Yes that is the plan, like anything I can't predict the future but I'm going to try and keep it at 125

[pt4u2nv]

I would definetly be interested in the 60 gr mold .

[Whiterabbit]

Dumb question, but AR-15 guys seem to shoot alot. ALOT. So with blocks that small, why not a 12 cav mold? I have no skin in this game. I'm just throwing that out there.

[runfiverun]

i'm gonna kick you in the shin.
i allready envision throwing a whole bunch back and having 6 different bell curves to deal with.
plus alloy manipulation,and hours of visual/weight sorting,and new load work up now.
and that's just to keep things in a 2" group.
now 12 cavity core molds i can get behind...

[JTknives]

ok the first post has been updated with 3d models of the mold blocks and sprue plate pivot design. let me know what you think.

[Mooseman]

I like the divot and individual pour holes personally because I use a bottom pour pot and like to keep the sprue as small as possible and keeps the lead from spilling all over the mold. The divot aligns the hole and pour spout much easier for us old geezers with failing vision.
